Just wondering if anyone has the Blue mountain Efis/sport in there flying aircraft for primary EADI and how do you like it. I'm wondering if you really need two units, One for ADI and one for HSI so you dont have to flip back and forth. I realize that your ADI page has Loc and GS on it but its not the HSI and it would take the place of my 106 indicator. If I went with only One unit I would also have a Standby ADI, Altimeter and Airspeed indicator. Also the unit is your autopilot head , Does anyone have this set-up? Thanks for the response in advanced.
